#you wouldn't join a destiel Facebook group (even a public one) just to tell ppl they're wrong

seeking out posts with opinions you know you won't agree with, to add long additions on why they're wrong, is widely seen as impolite and even combative on Tumblr. You're going to be met with hostility because people see it as a hostile act to begin with. similarly, it's considered rude to tag your hate of a ship or fandom content with the tag of that ship or content. Tumblr is structured to allow people to tailor their own communities and most people won't like you barging in going "actually, you're wrong." Most posts, unless actually specified, are not invitations for debate - building upon ideas, yes, and even asking questions is fine, but not "you are wrong." The culture is that we're doing our own thing over here, and you can stay over there, and coming into our spaces just to tell us we're wrong is rude. And embarrassing.
